"She acted so rude after the show ended last night. Mischa did not even seem to want to say goodbye to anyone. There were hardly any hugs or farewells.

"Mischa just never seemed into it from day one. And her behaviour certainly didn't win her many friends on set."

Reps for the star dismissed the reports as "absolutely not true".

They added: "She was thankful to have had the experience of being on the show."

After her departure Mischa, 30, admitted there had been "tension" with her professional dance partner Artem Chigvintsev and joked they should even have their own reality show.

Talking about how her experience on the show, Mischa told E! News: "I came straight out of a film and came into this, thought I was going to get this dance training.

"And it's been a fun experience and I've learned a lot from Artem.

"Team Black Velvet, we're a very interesting team. We should have had our own show."

Artem added: "I feel like this relationship has had a lot of up and downs. It's real. I feel it's a blessing that someone would express their feelings how it is. I don't want the BS. I don't want someone to play 'I'm so happy' when they're not.

"If you're unhappy, then tell me. I want that. I want it to be real.

"I felt like after having a rough start we finally got somewhere, and I'm happy with where we got."

The pair were voted off by the judges after securing just 18 points for their samba to the Miley Cyrus song Party in the USA.
